Then, Martin changed the win64 msi installer to exclude the ctypes package
when the _ctypes.pyd extension does not exist because it was not built.
In the meantime I have integrated patches (in the trunk) so that _ctypes
can be built for win64/AMD64, and does even work.
Can these changes be merged into release25-maint? IMO this is low-risk
because they contain only small changes to the files in Modules/_ctypes/libffi_msvc,
plus *some* changes to support the Windows LP64 model.
I would prefer to merge these changes into release25-maint, because I want to
also release the standalone ctypes packages from this branch (using it with
svn:externals from somewhere else).
The official Python 2.5.x win64/AMD64 windows installers should still *not*
contain the ctypes package, but they could install it separately.
